HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7515, 8331 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 7515, 8331 is 3 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 7515, 8331 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 7515, 8331 is 3.
HCF(7515, 8331) = 3
HCF of 7515, 8331 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7515, 8331 is 3.
Highest Common Factor of 7515,8331 is 3
Step 1: Since 8331 > 7515, we apply the division lemma to 8331 and 7515, to get
8331 = 7515 x 1 + 816
Step 2: Since the reminder 7515 ≠ 0, we apply division lemma to 816 and 7515, to get
7515 = 816 x 9 + 171
Step 3: We consider the new divisor 816 and the new remainder 171, and apply the division lemma to get
816 = 171 x 4 + 132
We consider the new divisor 171 and the new remainder 132,and apply the division lemma to get
171 = 132 x 1 + 39
We consider the new divisor 132 and the new remainder 39,and apply the division lemma to get
132 = 39 x 3 + 15
We consider the new divisor 39 and the new remainder 15,and apply the division lemma to get
39 = 15 x 2 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 7515 and 8331 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(39,15) = HCF(132,39) = HCF(171,132) = HCF(816,171) = HCF(7515,816) = HCF(8331,7515) .
